Specification of Letters Patent. Patnfed Sept, '7, 1920 Application at March 8. 1919. Serial No. 281,377.

this application is adapted to be applied to automobiles, street railway cars, locomotives, and vehicles of all kinds, for the purpose of removing snow, and the invention aims to provide novel means whereby a suction is created on each side of a plow, thereby enhancing the efiiciency of the plow and causing the device to work with great rapidity.

The invention aims to improve generally, and to enhance the utility of devices of-that type hereinafter described.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in bottom plan, a device constructed in accordance with the invention; Fig. 2 is a section on the line 2-2 of Fig. 1; and Fig. 3 is a fragmental section taken transversely through the plow, parts being omitted.

The device forming the subject matter of this application includes a frame, which may be made as occasion demands; As shown in the drawings, but not'necessarily, the frame includes side bars 1, adapted for connection with a vehicle of any kind,

(not shown). The side bars 1 are connected by cross bars 2, the cross bars being c011 nected, in turn, by a short longitudinal rail 3. The forward ends of the side bars 1 are connected to the wings 4 of a plow 5 including a point 6; The plow has a central longitudinal rib 7, and the wings 4 are supplied along their rear edges with outwardly extended flanges ,8. Openings 9 are fashioned inthe wings 4. Journaled for -ro-- tation in the openings 9 are suction fans,

comprising blades, 10 radiating from hubs 11 on shafts 12 journaled in curved brackets '14: connected to the rail 3 and in'bearings 15 on converging braces 16 projectingfroni the cross bars 2 above the side bars 1, the

bearings 15 being united by a tie 17,

v in the form of a rod.

Any suitable means may be provided for rotating the shafts 12. If desired, the'inner ends of the'shafts 12 may carry beveled. pinions 18 meshing into beveled pinions 19 on a cross shaft 20 ournaled in bearings 21 on the side bars 1 and on the longitudinal rail 3. If desired, the shaft 20 may be supplied at one end with a pulley 22 adapted to receive a belt 23, the belt 23 being extended rearwardly to any suitable source of power on the vehicle is assembled. a 1

In practical operation, rotation is imparted to the shaft 20 by way of the pulley 22 and the belt 23, or an equivalent conwherewith the structure struction. The beveled pinions 19 cooperating with the beveled pinions 18' drive the shafts 12, and the shafts 12 cause the fans, comprising the blades 10 torotate in the openings 9 of the wings 4 of the plow It is to be. observed that the upstanding central rib 7 and the flanges 8 form com partments on the upper sides of the wings 4E, and in these compartments, the suction is created. There is a diminution of pressure, on the top of the plow, on each side of the central rib 7, and, as a consequence, the

plow cooperates with unusual efficiency in working its way through the snow. ()ne of the fans rotates in a clockwise direction whereas the other fan rotates in a counter clockwise direction, the fans serving to force the snow outwardly, in opposite directions.

Having thus described the invention, what is claimed isz- A device of the class described including a plow having side wings providedywith openings; fans journaled in the openings; and means for rotating the fans to cause a draft outwardly through the openings, the plow having a central rib between the side as my own, I have hereto afiiXed my signature 1n the presence of tWo wltnesses.
